assuming that your producer level has 3,500,000 kilocalories of energy/area, use the rule 10 percent in energy transfer to calculate the amount of energy available at each consumer level. write those numbers to the right of each trophic level in the pyramid. show your calculations in the space below
Answer: I think you have to divide each level by 10 so the first level will stay the same and the rest go like this
3,500,000 divided by 10 equals 350,000
350,000 divided by 10 equals 35,000
and 35,000 divided by 10 equals 3,500

What effect does mitosis have on the diploid chromosome complement?
Answer:
sperm and egg in humans) would be haploid to allow for the new offspring to have the species' chromosome comlement. So, mitosis is the mechanism by which a diploid cell divides to produce two diploid daughter cells which have the same chromosome complement as the parent cell.

Con: The sexual reproduction is hard to get
It requires a lot of work just to create 1-2 organisms
It lacks speed

Which of the following disorders does not result from non disjunction in meiosis
Down syndrome
Turners syndrom
Klinerfelters
Sickle cell disease
Answer:
Sickle cell disease
Explanation:
Sickle cell anemia disorder does not result from non disjunction in meiosis. So, the correct option is D.
What is Sickle cell anemia?Sickle cell anemias are defined as a group of disorders that cause red blood cells to become malformed and break down.
With sickle cell disease, an inherited group of disorders, red blood cells are twisted into a sickle shape in which the cells die early, leading to a shortage of healthy red blood cells i.e. sickle cell anemia and blockage of blood flow which can cause pain i.e. sickle cell anemia cell crisis.
Infections, pain and fatigue are symptoms of sickle cell disease. This disease is not the result from non disjunction in meiosis like other diseases such as Down syndrome, Tuners syndrome, etc.
Thus, Sickle cell anemia disorder does not result from non disjunction in meiosis. So, the correct option is D.

Estimate the concentration of the sodium chloride solution that has the same water potential as the onions
Answer:
49, where the best fits crosses the x-axis where the mean percentage changes of the mass is 0
Explanation:
Water potential may be defined as a measure of the water's free energy in the solution. It is represented by symbol ψ (psi). It is affected by two factors :
-- pressure potential
-- solute
The water potential of pure water is zero.
In the context, the concentration of the NaCl solution that has same water potential as the onions where the line of the best fits crosses x-axis where the mean percentage changes of the mass is zero, that must be equal.
Assignment: Adaptations to New Environments Exploration
Directions: Read the descriptions of the four islands presented in the lesson.
1. List two new traits that each new species of rat might demonstrate as it adapts to the conditions on each island.
2. Introduce one of the four new rat species to another island and describe one challenge it would encounter and one success as it adapts to its new environment.
List the traits of each new species of rat

The rat on Island D:

Describe a challenge that would be encountered and a success of one of the new rats to another new environment (example: the rat living on Island B now moves to Island D).
Island A
The island is fairly flat with an occasional hill. The ground is made of soft dirt, and several species of shrubs grow toward the center of the island. There is no animal life on land, but the water around the island is teeming with fish. The island is surrounded by a coral reef, and the shore is sandy with no algae growing on it. Freshwater is available.
Island B
This island has a rocky shoreline. Numerous tide pools dot the island along the shore where the wave action is somewhat sheltered by rocky outcrops. The tide pools host barnacles, abalone, sea urchins, and crabs. Algae grow all around the island; however, the growth of algae is quite sparse in the tide pools where the various animals feed. The current is quite strong along the rocky outcrops where the algae grow best. Freshwater is available.
Island C
The island is somewhat barren. A few species of cactus thrive on the bare rocks, and a large, cactus eating tortoise inhabits the island. A species of very large birds nests on the island annually. The birds build their nests on the rocks and protect their eggs from the sun by standing over the nests with outspread wings. The nests are always found on the windy side of the island, which is somewhat cooled by offshore breezes.
Island D
This island is an extinct volcano. Vegetation on the island changes as the altitude increases. Grasses grow at the base of the volcano, but farther up the volcano’s slope, the grasses give way to low shrubs. Halfway up, the island becomes quite lush; tropical plants and trees dominate the landscape. At this altitude, the island experiences frequent rain showers. Two species of birds inhabit the island. One is a raptor that preys on the smaller birds. The other fishes the waters approximately one mile offshore. Both of the bird species nest in trees.

Which situation is an example of competition that could be found in the ocean?
two shark populations utilize the same fish population as their main food source
algae blooms decrease as the number of fish increase
lack of sunlight due to changes in the seasons restricts the growth of certain plants
plentiful oxygen leads to an increase in the number of reefs
Answer:
A. two shark populations utilize the same fish population as their main food source
I'm guessing this is from Marine Biology. I know this is an example of competition because two different groups of sharks are eating food from the same source. If one group gets to it first every time, they could leave the other group with no food. So it is a competition.

two shark populations utilize the same fish population as their main food source

Why does embryology suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common.
Answer:
In the examination of the embryological stages of various organisms, it appears to be very similar in their structure, for instance, all vertebrate embryos have gill pouch and that evolved in gills in fish and head and neck in others.
The tail of the vertebrates is also an example that is present during the embryological stage but later regressed in human and other have them. On this basis, it can be stated that embryology suggests an evolutionary relationship.
In a high pressure system, cool air ____________ and warms, and the weather is ____________ and ____________.
Answer:
Sinks; clear: dry.
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time.
The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.
The air pressure gradient which typically is the difference in air pressure between two systems affects the movement of atmospheric air. Consequently, this movement has a significant level of impact on the type of weather that is formed between low-pressure and high-pressure systems.
In a high pressure system, cool air sinks and warms, and the weather is clear and dry. Similarly, in low-pressure systems, warm air usually rises and then cools, thus, leading to the formation of clouds and precipitations.
The conservation of charge principle states that _________. Select all that apply.

Answer:
The correct answer would be - asparagine-arginine-stop (asn-arg-stop)
Explanation:
RNA codes are responsible for translated into amino acids that form an amino acid chain or protein. The translation is the process responsible for protein formation by translating mRNA sequences into amino acids with the help of tRNA and ribosomes.
Each three-letter RNA sequence also known as triplet code is responsible for a particular amino acid, certain codes called stop codons as they are responsible for the termination of translation of a particular chain.
AAU CGA UAG is the RNA sequence translated into asparagine-arginine-stop (asn-arg-stop) as AAU codes for asparagine, CGA codes for arginine and UAG is stop codon.

Rough-skinned newts produce a strong toxin called TTX as a defense mechanism against predators. Garter snakes can
tolerate a very limited amount of the toxin. However, several populations of garter snakes have recently shown an
increased tolerance for TTX. The different populations of snakes have independently acquired a gene variation that
allows them to better block the effects of the toxin.
